Why Linklaters?

We have extensive experience of a wide range of patent disputes across Europe.

Europe-wide patent expertise

A seamless service

Enforcing intellectual property rights that protect innovative products is an important factor for success in any industry. Together with our clients, we develop and implement patent enforcement strategies across Europe.

Our intellectual property lawyers have a strong track record in patent litigation cases. We help clients develop effective multi-jurisdictional litigation strategies, including launching and defending patent infringement proceedings in respect of their key products and technologies, and proactively commencing revocation and nullity actions in jurisdictions which may be more favourable to our clients.

Most of the cases we handle do not stop at the border. We work together closely across jurisdictions and provide a truly seamless service when acting in multi-jurisdictional litigation. We understand the characteristics and peculiarities of the key patent litigation venues and advise on how to utilise these to create strategic advantages.

With teams in Germany, the UK, France and Belgium, we are present in the important patent litigation jurisdictions in Europe; besides this, we have a good knowledge of the US litigation system and we are used to coordinating European and parallel US litigation, providing clients with a consistent approach, wherever they need us.

Linklaters’ lawyers have experience in co-ordinating litigation strategies with other advisers from our international network of leading IP lawyers. This allows us to use our experience as well as our shared knowhow while always taking relevant cultural specificities into consideration. Our structure is particularly adapted to managing complex cross-border matters and advising you on key cross-border projects like the Unified Patent Court (UPC).

Our experience of cross border patent litigation will allow us to help you define the best strategy to litigate before the UPC:

  • Choosing and securing suitable patents.
  • Choosing suitable defendants.
  • Choosing the right division (possibility of bifurcation).
